Insolight – Making solar energy affordable
Smart idea, using microlens plastic plate over CPV solar cells in a grid pattern under the plate, then shift the plate a little bit to track the sun. So basically you could do an artificial muscle actuator or MEMS to shift the plate, rather than some gigantic tracking heliograph CPV setup. Plate shift still limits tracking angles, but the cost is much cheaper.

Hrm, one type is a concrete trough with inflatable membranes as a general solar concentrator type, the other is a concentrator dish using an array of flat disc mirrors.

C7 design is interesting. Appears to be a concentrating solar PV rig, but single axis tracking? Makes anchoring the mirrors against wind easier.

Interesting collector design, based on on a blackbody cavity concept. Reduces costs since it doesn't use a vacuum tube receiver core, along with a low precision tolerant mirror reflector geometry. Seems to still require single axis tracking though, but 10 degrees is a lot easier to implement via ratchet mechanisms rather than continuous jackscrews.

IBM integrated microchannel chip cooling used to make solar cell panels with integrated liquid cooling, rather than sandwiched to a primary heat exchanger backing the solar cell panel. Supposedly reduces pumping power costs.

Title Page
Claiming a low cost double reflector mirror arrangement lets these guys do high concentration levels. Doesn't really solve the tracking problem, at first glance, but the same plastic shape trick could be used with a trough collector. Interesting that they use a clear plastic cover lens, but what about age or dust related degradation?

Airlight - Home
Oddball mix of inflatable mirror/lens assembly mounted on a lightweight fiber reinforced concrete frame. Essentially makes a closed, slightly pressurized container for the energy production components, to protect them from rain and air contamination. Though the ETFE film getting discolored due to age/exposure reducing power output might be a problem. The collector is universal, in the sense that the central core receiver can be either the CSP type using pressurized air for the heat transfer fluid (which nominally gets dumped through a gravel tank for heat storage), or a water cooled CPV receiver. Recently did work with IBM using IBM chip semiconductor manufacturing techniques to make CPV water cooled solar cell panels with integrated cooling in the silicon.via microchannels.

Semprius, Inc. :: Semprius is developing low cost, high performance concentrator photovoltaic (CPV) modules to make solar power generation economically viable in sunny, dry climates.
Interesting use of extremely small solar cells with concentrating optics. They claim they can run without heat fins for thermal management, but I have my doubts. Also claiming wide acceptance angles, but which might be true due to the optical geometry of the concentrators. The microprint transfer system allows wafer reuse, which is interesting...

I think they are basically trying to sell a thin film prismatic lens array with spectrum waveguiding as an aftermarket upgrade to existing solar PV systems. Wait, now they are doing photoelectrochemical hydrogen production with the intent of synthetic natural gas production? Seems they are close to the magical 1.23V open circuit voltage needed for direct solar hydrogen production.

Solar Thermal Electrochemical Photo (STEP) Carbon Capture could Reduce Atmospheric CO2 to Pre-industrial Levels in Ten Years
Using an externally electrically driven molten lithium carbonate cell to crack CO2 down to C or CO, CO being fed into synthetic fuel processes, C for solid state long term sequestration/storage or as nanotube feedstock. Uses Solar CPV with thermal recovery to heat the cells and drive them electrically. Absolutely no mention of how the CO2 would be captured for input into the electrolysis cell (basically the same as a MSFC fuelcell, only without the hydrogen fuel) though.
